Fig. 8 isa side view of Fig. l.

Similar reference characters refer to similar parts throughout theviews.

vAll of the sectional views are drawn to a *v larger scale.

The apparatus shown in the accompanying drawing comprises, principally,thebase A, the copy support plate B, the copy moving means C, the copyindexing means D, and 9o the auxiliary copy holder E.

The upwardly extending ears 10 are provided on the base A and have anopening therethrough forv the purpose appearing presently. The forwardlyextending arm l1 is provided on the base A and has the adjusting screw12 threaded therein and also has the spring 13 resting in acountertionally grip bore therein, and also has the pad 14 resting in acounterbore therein, and also has the ears through which the pivot screw16 passes; the purpose of the members 12, 13, i4. and 1G will appearpresently.

The bottom of the base A is provided with the feet 17 of rubber or othercushioning or nonabrasive material.

The plate B is formed of sheet metal with the side edges bent down toform the longitudinal flanges 18 to stiffen the plate lengt tudinallyand to provide a means for supporting other members of the apparatus aswill appear presently. The top edge of the plate B is also bent down toform the transverse fiange 1'9 to sti-'tten the plate transversely andto provide a base to support the copy moving means C.

The adjusting strip 2() is interposed between the top of the plate B andthe bottom of the copy moving means C.

rlhe copyv moving means C has the frame 21 resting on the adjustingstrip 20 and also has an upwardly extending ear 22 at each end thereof.The frame 21 is secured to the flange 19 by the screws 23 which alsopass through the strip 20. rllhe copy roller shaft 24 is journaled inthe ears 22 and extends a short distance beyond these ears and isprovided with the knob 25 on each end thereof.

The plates 2G are secured to the outside of each end of the frame 21 andext-end forward of the frame.

The square shaft 27 extends between the plat Js 2G and has the roundends 28 journaled in the forward end of the plates 26.

The lower portion of each of the brackets 29 encompasses the squareshaft 27 and the upper portion thereof supports the lower sight bar 30which extendssubstantially the full length of the frame between the ears22.

The lower portion of each of the brackets 31 encompasses the squareshaft 27 and the upper portion thereof is formed as a journal for thepin 32 to which thev roller 33 is secured. The lower square portion ofach bracket 31 is first made a little smaller than the shaft 27 and is,preferably, provided with inherent spring tendency to fric- Y this shaftso that these brackets 31 with the rollers 33 journaled therein can bemoved along the shaft 27 to any desired longitudinal position toaccommodate different widths of copy and to remain in this adjustedposition without manijmlating any releasing or locking means.

rlhe eye bolts 34 are secured to the shaft 27 near the end of the squareportion thereof.

The rollers two in the present iustance with the space 36 between them,are secured to the shaft 24 and extend between the ears 22.

The tension springs 37 have one end thereof secured to the eye bolts 34and the other end thereof to the ears 22. The object of these springs isto normally tend to rotate the shaft 27 to hold the rollers 33 againstthe rollers 35 and thereby hold the copy against the rollers 35.

The handles H are secured to the shaft 27 and serve the purpose ofmanually rotating the same to remove the rollers 33 from the rollerswhen it is desired to release the copy or for other purposes.

The upper sight bar K has the ends bent down to form the ears 38 whichare hinged to the cars 22 by the hinge screw 39.

It is observed that the upper sight baras well als the lower sight barare hinged to the frame 21. T his arrangement permits either one or bothbars to be moved or swiveled and thereby increase or decrease the widthof the sight space 40, or to swivel the upper sight bar out of the way,or for other purposes.

The sprocket 41 is secured to the roller shaft 24 and occupies the space36' between the rollers 35.

A lug 42 is secured to the lower end of the flanges 18 of the plate B bythe screws 43 and these lugs are disposed inside of the ears 10 and inalignment and in contact therewith.

A hinge joint is formed between the bot-- tom of the plate B and theears of'the base A, on each side of the plate B, to permit the plate Bto be swiveledy on the base A for the purpose of angular adjustment ofthe plate B to suit the convenience of the operator.

Each' of these'hinge joint-s (Fig. comprises the sleeve 44 passingthrough the ear 10 and through the lug 42 and one end thereof isprovided with the head 45 bearing against the lug 42. The nut 46 isthreaded to the other end of the. sleeve 44 and bears against the ear10.

By means of these nuts 46, the hinge. joints can be adjusted so thatsufficient friction exists between the members thereof to permit theplate B to be swiveled on the base A to adjust the copy to theVconvenience of the operator and to retain the plate B in any adjustedposition wit-hout manipulating the adjustment of these hinge joints.

This swivel joint arrangement permits the operator to adjust the copy todesired position and the friction feature of. these joints permits ofsuch adjustment and at the same time holds the plate B in whateverpositionit has been adjusted to. This swivel joint feature also permitsthe plate B to be swiveled way down to substantially parallel positionwith the arm 11 so that the apparatus as a whole may be folded up into'compact form for shipment or storage.

The spacer shaft 47 is journaled in the sleeves 44 and has the collar 48pinned to one end thereof to prevent longitudinal movement of the shaftin one direction.

The drive cup 49 is secured to the ot-her end of the shaft 47 by the pin50 passing through the hub 51 and through .the shaft 47. The end of thehub 51 bears against the sleeve 44 to prevent longitudinal movement ofthe shaft 47 in the other direction.

The cover 52 is journaled on the other end of the shaft 47, adjacent totlie cup 49 and is held in position by the nut 53 threaded to the end ofthe shaft 47.

The bracket 54, secured to the base A, has the neck 55 extending upwardthrough the space 56 provided for that purpose between the open end ofthe cup 49 and the cover The upper end of the neck has the projection 57extending into the cup 49 for the purpose appearing presently.

The lever 58 is fulcruined on the base A between the ears 15 by thepivot screw 16.

The rear end of the lever 58 carries the pivot screw 59 which isthreaded into the cover 52 and which has the pilot 60 extending into thecavity of the cup 49. The purpose of this pilot is to confine the roller61 between the block 62 and the inner wall 63 of the cup 49 as seen inFig. 7, so that the` roller can not fallout of place when the apparatusis held in different positions.

The block 62 is riveted to the cover 52 in an inclined position so thatthe side 64 thereof forms a wedge face in relation to the wall 63. y y

The roller 61 lays loosely against the wall 63 and against theprojection 57 and does not contact the side 64 when the index mechanismis in normal position as seen in Fig. 7.

When the index mechanism -is in this position, a rotative movement ofthe cup 49 in either direction, permits the roller 61 to rotate on thewall 63 without contacting the side 64 of the block 62 since the cover52 is rotatable on the shaft 47 and is now held against rotation by thelever 58, thereby retaining the roller 61 loosely in the cup 49.

When the front end 6.5 ofthe lever 58 is pressed down, the rear end 66moves upward as shown by the arrow in Fig. 7. Since this end 66 issecured to the cover 52 by the screw 59, this upward movement of thisend 66 rotates the cover 52 iii the direction of the arrow shownthereon. Since the block 62 is secured to the cover 52 it rotatestherewith. y

When the block 62 so .moves with the cover 52` the clearance 67 is firsttaken up and the roller 61 is then wedged in between the side 64 of theblock 62 and the wall 63 of the cup 49 whereby the cup 49 is locked tothe cover 52 and must rotate therewith. The shaft 47 must rotate withthe cup 49 since they aresecured to each other by the pin 50.

Upon releaseof the front end of the lever 58, the spring 13 returns therear end 66 to original position.- Vln such return movement, the rolleris not gripped between the side 64 and the wall 63 and can freely movedown, due to gravity, until it abuts the projection 57 as seen in Fig.7. rllie end k66 of the lever then moves a little further The sprocket68 is secured to thespacer sha-ft 47 and the sprocket 41 is secured tothe roller shaft 24 in alignment with the sprock-r et 68. The chain 7()connects both fof these sprockets. l

Then` a copy is placed into this apparatus,`

between the rollers 35v and 33, it may be adjusted in the sight space 40by rotating the roller 35 by means of the knobs 25. This rotation of therollers 35 also rotates the sprocket 41 which, in turn, rotates theshaft47 and the cup. 49 thereon through the chain 70 and the sprocket 68. lAs previously stated, the cup 49 can rotate ineither direction withoutaffecting the index mechanism, therefore, the adjustment of the copy inrelation to the sight space can be carried out without affecting the'index mechanism. y

After the copy is so adjusted, the adjusting screw 12 is manipulated sothat the index mechanism rotates the rollers 35 in conformity to theline spacing on the copy when the end of the lever is pressed downiintil it contacts the adjusting screw 12.

After the index mechanism is so adjusted, y

llo

each manipulation of the lever 58 moves the copy according to theadjustment while the Y copy vcan be adjusted independently by means ofthe knobs 25 without affecting the index mechanism. Y

The auxiliary copy holder means E is hinged to Vthe plate B and extendsforward thereof.

The brackets 71 have the lower poi-tions thereof secured to therespective flanges 18 by the screws 72 and the upper ends thereof areformed with the vjournal portions '73 for the bar 74. l Y .Each of thesejournal portions has the flange 75 and the screw 76 passingthrough thisHange and is threaded to the portion adjacent to this flange. Thisarrangement permits the journal to be adjusted by means of the screw 76so that there is just su'liicient friction between the bar 74C and theportion 73 to permit the bar 74 to be rotated in the journal 7 3 but toremain in any position it has been rotated or adj'usted to.

The bar 74 has the end portions adapted to the journals 73 as stated,and also has the side portions 77 extending forward of the plate A, andalso has the longitudinal front portion 78. rl`he journal at 73 permitsthe portion 78 to be moved up and down in front of the plate B.

The bracket 79 has the lower portion SO formed to encompass the portion78 of the bar 74 and is provided with suliicient inherent springtendency to frictionally engage this portion'78 to permit the bracket 79to be rotated thereon and to remain in whatever position it has beenrotated to.

The auxiliary copy holder Sl is supported on the bracket 79 and has theclips 82 to hold the same thereon.

This arrangement of the auxiliary copy holder means permits the copyholder 8l to be put on or taken off of the bracket at will, and alsopermits this copy holder to be adjusted up and down by means of theswivably journaled bar 741:, and also permits this copy holder to beadjusted angularly to suit the convenience of the operator, and alsopermits this copy holder to be removed from the apparatus and furtherpermits the bar 74 as well as the bracket 79 to be folded close to thefront of the plate B for the purpose of shipment, or storage, or to havethis mechanism o'ut of the way when only onel copy is to be supported onthe apparatus.

lVhen it is desired to adjust the chain 70, the adjusting strip 2O isreplaced by one thinner or thicker as required.
